You can use the guide number system (see How can I calculate the effect of non-TTL flash on exposure?), possibly in combination with your camera's meter or a separate incident flash meter. But if you have several lights, modifiers, and are trying different poses and positions, trial and error is probably actually easier and faster. As you practice, it'll ...


Open aperture metering also allows open aperture focusing, which is perhaps even more significant. The wider a lens is opened, the faster and more accurate a phase detection auto focus system can be. Note that open aperture metering became popular well before digital cameras hit the mainstream market. It became popular when automated focus systems started to ...


Legacy lenses tend to have a mechanical and or electrical coupling that tells the camera where the aperture ring is set without actually stopping down, so the meter in cameras built for this can take a reading at full aperture, do a quick calculation based on the selected f number. When you press the shutter release, the mechanical linkage causes the ...


You can use a set of Yongnuo YN-622C triggers to maintain most E-TTL functionality when your 430EX is off camera. Each YN-622C unit is able to act as either a transmitter or a receiver. I prefer to use the YN-622C-TX on camera as it has an LCD that makes setup and changing settings much easier. The YN-622C-TX is a transmitter only. You would then need only ...


If you want remote power control of the 430EX, you could use TTL-capable radio triggers (e.g., RadioPopper PX, PocketWizard TTL, Yongnuo YN-622C, Pixel Kings, Phottix Odins), but these might have only limited control over the 430EX, since some of them use the camera menu flash control signals to communicate settings to the flash. For example, with YN-622 ...
